Hi,

I have just re-mounted my 355/9 G-claron in an Copal 3 shutter with a aputure scale of a lens with 5.6 as the largest F no.

OK now.. would it be approx. right to convert,
5.6 8 11 16 22 32 45 64 to
9 11 16 22 32 45 64 90 ??

and my G-Claron 240/9 remounted into a copal polaroid 4.5 and converting
4.5 5.6 8 11 16 22 32
9 11 16 22 32 45 90


And if NOT (which most probably is the case ) how far off would I be??
Corrections are appriciated!!

Best regards
Morten
